There are five oceans on Earth. Each ocean leads into the next, creating one huge expanse of water, covering 71 percent of Earth's surface.

The smallest ocean is the Arctic Ocean, with an area of 5,880 sq. mi. (9,485 sq km).

The Pacific Ocean is by far the biggest ocean. It covers nearly one-third of Earth's surface!

72Tan seeds:24red seeds

Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.
